My friend also has the habit of getting up early and running in the morning, which may be the reason why she has been staying in the air-conditioned room. Recently, she began to feel a little stiff and uncomfortable in her waist and shoulders. Then she jogged for several days, feeling relaxed and in good spirits. But a week later, her legs and feet began to become heavy and she couldn't run if she wanted to.
According to experts, this is discomfort caused by excessive exercise. Because exercise can speed up metabolism and produce a lot? Active oxygen? This is a substance that promotes human aging.
Excessive physical exercise can lead to muscle soreness, articular cartilage wear and arthritis.
Excessive exercise can also lead to rapid heartbeat, high blood pressure, lack of oxygen, fainting, and even fatal if it is serious.
A study in Denmark shows that jogging three times a week, the total amount is controlled at 144 minutes, and the speed is controlled at slow or medium speed. If it exceeds this amount, it will affect human organs and immune system, so fitness will become harmful.
Generally speaking, running is not recommended in the following situations.
0 1
Don't run when you are sick. Once, a little girl caught a cold and was taken to run by her parents, thinking that this would cure her cold. As a result, her cold became more and more serious. As we all know, the most important thing for people after catching a cold is to rest. Running consumes physical strength, which is not conducive to the recovery of the disease.
02
Don't run at the beginning of pregnancy. Because of the changes of body hormones in early pregnancy, the implantation of the fetus is not stable enough to run.
03
Try to run uphill, not downhill, because when running downhill, the impact of the ground on the feet, ankles, knees and legs increases (about 4 to 5 times the weight). When running uphill, the impact will be much smaller, which is more conducive to strengthening the strength of the thigh and helping to stretch the achilles tendon. When you run down the hill, you should reduce your stride.
04
Don't run without doing warm-up activities. The internal organs and limbs of the human body need an adaptation process from a relatively static state to more intense activity. Therefore, people should also do proper warm-up activities before running, so that the physiological functions of the body can coordinate their work under the condition of exercise. If you don't do warm-up activities before running, joint ligaments and tendons will often be sprained during long-distance running. It is more likely to happen especially when running nervously together.
In addition, when people with poor physical fitness accelerate, they should start with small steps. Running acceleration is also a programmed operation of human machine, not just gnashing your teeth. By adjusting breathing, you can make running time last longer and exercise effect more obvious.
